This invention relates to valve mechanism for air compressors and has for its primary object the provision of a new and novel and positively functioning structure character- 5 ized by instrumentalities that render the structure useful either as an inlet valve means or an outlet valve means for the compressor, and wherein two of said valve means will function in the system in time with regular operations thereof by simply inversely positioning one of said valve means with respect to the position of the other said means without the necessity of changing the physical construction of either of said means.

I A further object of the invention is to pro- 7 vide a valve mechanism which will be posi tive of action, simple of operation, strong and durable and of a design that insures its long life while in service.

A further object of the invention is to provide valve mechanismwhose valve will be always definitely related to its co-acting seats and wherein the valve and said seats can be manually ground by manual operations of the valve.

Other objects and advantages will more clearly appear as the description proceeds.

In carrying the invention into practice, use is made of a mechanism 10 consisting of two mating elements 11 and 12, which are threadedly connected at 13 for the accommodation of one element within the other, as shown to advantage in Figure 4. The adjustment of one of said elements within the mating ele- 7 is a similar, but inverted, View of ment is limitedthroughthe provision of an annular flange 14011 the element ll, the same adapted to come in contact with one edge of the annular wall ,ofathe element 12. This causes a spacez15 to be provided between the portway .16. and a plurality of radial port- Ways1 17. cThe said elementlis provided with a reducedflannular skirt 18 which is spaced. fromth'e annular wall ofltheelement 12at one side of the aforestat'ed radial I port-Ways. This skirt is :also provided with an annular cup ordepre'ssionlQ and at the joinder. of the Walls of the cup with the body of the element llthere is formed a flat valve seat 20 disposedin concentrierelation to the port-way 16.

In order thatthis can be accomplished, it isdesirable to supply the disks with a stud 24 having a kerf 25 for theinsertionof the aforementioned instrument. i

From the nature of the mechanism, taken in conjunction" with the characterizing features of the parts as above explained, it manifestly follows that the mechanism can be used as an illustration at thepoint A of the compressor 9 as an intake valve, while a duplicate one of the mechanisms can be employed at the point B to function as an outlet. All that is neces sary in order to permit the invention to perform its service in the manner stated is that two of the mechanisms shown in Figure 4 be, res tively, incorporated in the compressor wi one of the mechanisms positioned in an inverse order to the other.
